SCREEN.

SPECIFICATLON forming part of Letters Patent No. 712,971, dated November4, 1902. Application filed October 1l, 19,00. Serial No. 32,7] 9. V(Nomodel.)

To all whom it muy concern:

Be it known that I, HENRY LE FEVRE SAN-k DERS, a citizen of the UnitedStates, andfa resident of Jersey City, in the countyv of Hudson andState of New'Jersey, have invented a new and Improved Screen, of whichthe following is a full, clear, and exact description.

rlhis invention relates Ato a window-screen for keeping out iiies andother insects, which screen involves certain novelties of construction,permitting its ready adjustment toY av ily adjustable to windows of anysize, when.

in place is perfectly rigid andis adaptedto slide on strips on thewindow-frame to raise or lower or otherwise dispose it, as desired.

This specification is the disclosure of one form of the invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is an elevational view of the invention. Fig. 2 is a section onthe line 2 2 of Fig. l. Fig. 3 is a section on the line 3 3 of Fig. l;and Fig. 4 is a section similar to that in Fig. 2, except that the partsare shown in extended position. Y

Referring to the drawings, the screen is made up of two sections, eachof which comprises a vertically-extending end rail ct and top and bottomrails b and c. These rails b and c carry the screen or netting d, andthe ends of the rails b and c'opposite the rail a are provided with abar e, which extends between the top and bottom rails b and c to connectthem with each other and Which serves also as a means to which the outeredge of the netting d may be secured. The rails h and c of each sectionare arranged to slide on each other, so as to adjust the width of thescreen, and these parts are held to move in the proper manner andfastened rigidly when in desired adjustment bythe two bolts f, which arecarried by the rails b and c of one section and project throughlongitudinallydisposedslots g in the rails of the other section. Bythese means the sections may be moved freely on each other, but theyareheld to move true, and by tightening the nuts on the bolts fthe twosections may be clamped .firmly together, so as to form practically arigid frame. The'screen when adjusted to the window and thevsectionsfastened together 5 5 may slide freely on strips on the windowframe withthe same facility as a screen formed of a single rigid framing which hasto be made especially for the window with which it is used. of theseciionwhich carries the boltsfare provided with extensions b' and c attheir ends, which serve tolie against the top and bottom rails of theother section, in which The top and bottom rails h and c 6o I othersection the slots g are formed, and when theV sections. are drawn farapart, as illustrated in Fig. 4, the extensions b' ando pass over theends of the slots and cover the saine, so as to prevent insects frompassing through the slots.

to joining the top and bottom bars and to carrying the adjacent edge ofthe screen serve, further, to effect tight connections between the twosections of the screen, so that The bars e, in addition 7o insects maynot pass between these parts.

This is illustrated in Figs. 2 and 4, where each bar e is illustrated'asengaging the netting of the section other than that on which the bar iscarried. One of the top rails may be provided, as is shown in Fig. 3,with a 8o ledge h3, which overhangs the other top rail and effects asnug connection, so that the window-sash may be moved down firmly on thescreen and a tight iit secured. The frame of the screen being rigid, asabove explained,

no other support for the inner ends of the vrails b and c is necessary.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A sliding and extensible screen, consisting of twosections movable one upon the other, each section comprising an end railand a top and bottom rail secured to the end rail iiush with one sidethereof, the end rails being formed of a single piece and of a thicknessabout equal to the combined thickness of the top rails or bottom rails4and provided with longitudinal grooves in their outer edges to receiveand slide upon a guideway on the rco Window-frame, the top and bottomrails of one section being longer than the rails of the other, theshorter rails'being provided with longitudinal slots and the longerrails with two bolts each, said bolts passing through the slots of theshorter rails and having nuts on their ends, the ends of the longerrails serving to close the slots ofthe shorter rails when the screen isextended, and a netting secured to each section, whereby a screen isproduced which can be adjusted to t any Window and when adjusted thesections can be rmly secured together to form practically a rigid frameso that it will slide freely on the guide- Ways on the Window-frame, asset forth.

2. A sliding and extensible screenconsisting of two sections, movableone upon the other, each section comprising a top and bottom rail, anend rail to which l[he top and bottom rails are secured flush with oneside.

thereof, a bar secured to the inner ends of the top and bottom rails andprojecting beyond the inner edges of the same, the end rails beingformed of a single piece and of a thickness about equal to the combinedthickness of the top rails or bottom rails and provided withlongitudinal grooves in their outer edges to receive and slide uponguideways on the window-frame, the top and bottom rails of one sectionbeing longer than the rails of the other section, the shorter railsbeing provided with longitudinal slots and the longer ones with twobolts each, said bolts passing through the slots of lthe shorter railsand having nuts on their ends, and a netting for each section, as setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY LE FEVRE SANDERS.
